Snapshots names doesn't contain view name

[AllDmeat]

Context 🕵️‍♀️

We've been using swift-snapshot-testing for quite a while, but without Prefire. swift-snapshot-testing saved snapshots with for each view into separate folder:

ModuleName
└── Tests
    └── __Snapshots__
        ├── AuthViewTests
        │   ├── newUser.png
        │   └── existingUser.png
        └── CartViewTests
            ├── emptyState.png
            └── errorState.png

What 🌱

Prefire saves all snapshots into single same folder, so resulting structure is like this:

ModuleName
  ModuleNameTests
    __Snapshots__
      PreviewTests
        newUser.png
        existingUser.png
        emptyState.png
        errorState.png

We are using #Preview to specify name of a preview/snapshot like this:

#Preview("newUser") {
    // my preview
}

This may lead to names being overlapped between multiple views and it actually already did happen in our project.
To avoid this we duplicate our view name into preview name like this:

#Preview("AuthView newUser") {
    // my preview
}

That solves the issue, but creates unnecessary duplications of a view name in canvas previews.

Proposal 🎉

I believe saving snapshot into folder named after source file name #Preview originated from can solve this issue:

ModuleName
└── ModuleNameTests
    └── __Snapshots__
        ├── AuthViewTests
        │   ├── newUser.png
        │   └── existingUser.png
        └── CartViewTests
            ├── emptyState.png
            └── errorState.png

Hi! I like this change. It doesn't look complicated. I'll try to make it in the next release!
