mq: fix qpush --move with comments in series file between applied patches

The 'start' variable pointed to qtip in self.series, but it was used for
indexing self.fullseries.

When fullseries had holes and the patch was moved to self.fullseries[start]
it would end up too early in self.series and it could thus not be
found in self.series[start:] and it would crash.

Now the 'fullstart' index in fullseries is found used instead.
