mirror:  'lvconvert --resync' should reset LV_NOTSYNCED on corelog mirror

When reformatting the 'lvchange_resync' code in commit
05131f5853e86419d9c726faa961b8d012298d9c, a '!' should have been removed
from the condition that checks for the LV_NOTSYNCED flag on a corelog
mirror LV.  The presence of this '!' caused the LV_NOTSYNCED flag to be
cleared when it wasn't present and left when it was present.

It is not allowed to add images to a 'mirror' or 'raid1' LV if the
LV_NOTSYNCED flag is set.  We add some up-convert tests to ensure this
behavior is being enforced and that the LV_NOTSYNCED flag is being
properly cleared by 'lvchange --resync'.

(Not updating WHATS_NEW because this is intrarelease.)
