Fix empty() bug on DBPrefix #2205

Description
When Forge runs dropTable() it will check for and strip the DBPrefix from a table name if found. It does this check via (! empty($this->db->DBPrefix) ... but since DBPrefix is acquired through BaseConnection's magic __get without a corresponding __isset() empty() returns false even when it isn't empty. Because of the magic getter and the initial property we can be sure DBPrefix will always be there so it is fine to test ($this->db->DBPrefix directly. Might consider adding __isset() to BaseConnection at some point.

Since
#2206 was partly caused by this Forge issue I'm adding the fix here as well:

  • Moved migration rollback before the drop-table loop

@lonnieezell I think this one is a straight bug fix, unless you would like __isset() added to BaseConnection.

It was brought up in another issue, but adding _isset() is probably a good idea.
