Fix for Bug#32538: View definition picks up character set,

Browse Source 
but not collation.

The problem here was that text literals in a view were always
dumped with character set introducer. That lead to loosing
collation information.

The fix is to dump character set introducer only if it was
in the original query. That is now possible because there 
is no problem any more of loss of character set of string
literals in views -- after WL#4052 the view is dumped 
in the original character set.
