wizard: fix save users changes after reviewing dump dir files

If the user reviewed the dump dir's files during reporting the crash, the
changes was thrown away and original data was passed to the bugzilla bug
report.

report-gtk saves the first text view buffer and then reloads data from the
reported problem directory, which causes that the changes made to those text
views are thrown away.

Function save_text_if_changed(), except of saving text, also reload the files
from dump dir and update gui state from the dump dir. The commit moves the
reloading and updating gui functions away from this function.
