Fixed bug mdev-4063 (bug #56927).
This bug could result in returning 0 for the expressions of the form
<aggregate_function>(distinct field) when the system variable
max_heap_table_size was set to a small enough number.
It happened because the method Unique::walk() did not support
the case when more than one pass was needed to merge the trees
of distinct values saved in an external file.
Backported a fix in grant_lowercase.test from mariadb 5.5.
