Improve RenameExpectSameToExpect rule to apply to expect.all

[zainab-ali]

The RenameExpectToExpectSame scalafix rule rewrites expect(...) calls to expect.same, but misses several other rewrite opportunities:

• It doesn't to do the same for expect.all. Users relying heavily on expect.all have no easy migration rule, and poor error messages from it.
• It doesn't apply to nested boolean assertions with && and ||. Users can wrap these in clues, but their errors and code would be cleaner if these were rewritten to weaver's and and or.
• It doesn't apply to the cats ===

This changeset amends the rule to apply to:

• expect.all by rewriting equality assertions into expect.same(...).and(...) calls
• === by rewriting it to expect.eql.
• && and || by rewriting them to expect(...).and(expect(...))
• expect(if cond a else b) by rewriting it to if cond expect(a) else expect(b))
• expect(a match { case b => c }) by rewriting it to a match { case b => expect(c) }

It also improves AddClueToExpect to add clues to negated statements and type applications.
