Minor improvements to Connection

[andrewsayre]

Description:

Makes some minor improvements to the connection logic:

• Names tasks
• Uses suppress instead of try/except/pass
• Removes unnecessary catching of derived exceptions (e.g. ConnectionError is derived from OSError which we were also catching)
• Modified test to wait out reconnect task
• Test coverage is now 100%
