It should be doing the opposite in cases where it's preceded by whitespace (e.g. "Hit ’Em Up"), and possibly (but arguably) lowercasing if it's preceded by anything else (e.g. "Get’em", "187’em").

There already appears to be a test case for this in the code, but I guess it's not surfacing for some reason?

input: 'Hit \'em \'til they go \'way \'n stuff!',
expected: 'Hit \'Em \'Til They Go \'Way \'n Stuff!',
message: 'Standalone contractions are uppercased, except if 1-char',
