The regex for removing the email address of the last translator from
PO-files contained two bugs causing it not to match:
1. It didn't account for text after the email address and PO-files
from Transifex contain the year of the last translation there.
2. It expected a second `\\n"` at the end of the line, instead of `\n"`.
This commit fixes both of these issues and simplifies the regexes. It
also ensures that the text after the email address is kept as well.
