shelve: adds restoring newly created branch (issue5048) (BC)
Before this patch shelve never preserved branch information,
so after applying unshelve branch was the same as it was
on working copy no matter in which branch shelve took place.
This patch makes bare shelving(with no files specified, without
interactive,include and exclude option) remembers information if
the working directory was on newly created branch ,in other words
working directory was on different branch than its first parent.
In this situation unshelving restores branch information to the working
directory.
