Migrate Swiftdeps-based Tests with Poorly-Formatted Fingerprints

These tests were using fingerprints name 'after', 'before' and 'same', which are far too short to resemble a fingerprint value, which must be 32-bytes. Migrate these files so that

'after' -> 'afterachangewasmadetoswiftsource'
'before' -> 'beforechangewasmadetoswiftsource'
'same' -> 'sameasiteverwassameasiteverwassa'

There is otherwise no change to the contents of these files.
