Name swapping issue with extra whitespace

[RocketMan]

Multiple whitespace characters following the comma in an artist name perturbs the name swap algorithm.

In the following playlist, the artist Barbara Dane is name-swapped for some albums, but not others:

It turns out in the cases where there is no nameswapping, the artist's name is keyed as Dane,\b\bBarbara (two spaces following the comma). In the cases where it works, it is Dane,\bBarbara (one space).

Expected: Name swapping should work without regard to the number of spaces.
