bug #28309 First insert violates UNIQUE constraint - was "memory" table empty?

Browse Source 
If we have lower_case_table_names == 2 (usually on case insensitive file
systems) we sometimes make 'homedir' part of the path sent to the
handler into lowercase. So in this case HEAP engine couldn't properly
find and remove HP_SHARE, what caused the bug.
