[Integration][GItlab] Revert changes made in attempt to resolve race conditions (#1343)

# Description

What - Revert changes made to the integration in 0.2.1

Why - 0.2.1 made significant changes to real time events handling..
I'm releasing this in attempt to role out chances that the issue of
merge request events not syncing was sparked by 0.2.1 and if it actually
is, then we'd have to trace the background of the problem 0.2.1 sought
to solve and re-solve.

How - Restore state of real time events prior to 0.2.1

## Type of change

Please leave one option from the following and delete the rest:

- [ ] Bug fix (non-breaking change which fixes an issue)
- [ ] New feature (non-breaking change which adds functionality)
- [ ] New Integration (non-breaking change which adds a new integration)
- [ ] Breaking change (fix or feature that would cause existing
functionality to not work as expected)
- [ ] Non-breaking change (fix of existing functionality that will not
change current behavior)
- [ ] Documentation (added/updated documentation)

<h4> All tests should be run against the port production
environment(using a testing org). </h4>

### Core testing checklist

- [ ] Integration able to create all default resources from scratch
- [ ] Resync finishes successfully
- [ ] Resync able to create entities
- [ ] Resync able to update entities
- [ ] Resync able to detect and delete entities
- [ ] Scheduled resync able to abort existing resync and start a new one
- [ ] Tested with at least 2 integrations from scratch
- [ ] Tested with Kafka and Polling event listeners
- [ ] Tested deletion of entities that don't pass the selector


### Integration testing checklist

- [ ] Integration able to create all default resources from scratch
- [ ] Resync able to create entities
- [ ] Resync able to update entities
- [ ] Resync able to detect and delete entities
- [ ] Resync finishes successfully
- [ ] If new resource kind is added or updated in the integration, add
example raw data, mapping and expected result to the `examples` folder
in the integration directory.
- [ ] If resource kind is updated, run the integration with the example
data and check if the expected result is achieved
- [ ] If new resource kind is added or updated, validate that
live-events for that resource are working as expected
- [ ] Docs PR link [here](#)

### Preflight checklist

- [ ] Handled rate limiting
- [ ] Handled pagination
- [ ] Implemented the code in async
- [ ] Support Multi account

## Screenshots

Include screenshots from your environment showing how the resources of
the integration will look.

## API Documentation

Provide links to the API documentation used for this integration.
