core: Replace newline/tabs after paste is accepted

Instead of replacing newline/tabs when paste is started, do it when the
paste is accepted instead. This makes a difference if you paste again
while the paste confirmation is active, where instead of running it
again for each paste, it will now be run for all the text at the end.

For now this doesn't make a practical difference, but the next commit
will remove the final newline when multiple lines are pasted too, which
we only want to do for the final paste.
