Use precise snapshot names when pruning

[bahmutov]

It is not enough to just check prefix when pruning snapshots - because it will leave bunch of snapshots!

https://github.com/bahmutov/snap-shot-core/blob/master/src/prune.js#L25

Situation:

Imagine a test initially like this one

it('works', () => {
  snapshot('foo')
  snapshot('bar')
})

The snapshots saved will be

• works 1
• works 2

Then we remove the second snapshot, leaving

it('works', () => {
  snapshot('foo')
})

BUT when we prune we only pass the name of the TEST "works", and then check all snapshot names if they start with that test name. Because both works 1 and works 2 start with works we assume that they should remain in the file. This is wrong.

need to keep track of ALL exact snapshot names for each file
