name-parser: Fix Python2 compatibility

[why]
The naming has bizarre blanks strewn in sometimes,
or is all caps. For example
`C a s k a y d i a   C o v e` or
`CASKAYDIACOVE-Regular`

[how]
When run under Python2 all strings are unicode strings because
`unicode_literals` is imported by `font-patcher`.
Unfortunately the code checks for type str; but that will all become
type unicode with the import.

One check is suboptimal anyhow and can be dropped, while the other is
turned around.
