Revert back to RegEx for dropping enum columns (cakephp#1086)

Merge remote-tracking branch 'pr0ggy/issue-1086-sqlite-dropcolumn-issue'

Fix invalid changeColumn regex causing deletions

This fixes a pretty serious bug in the Phinx SQLiteAdapter that causes columns to be destroyed when you're removing the default value of `''` from a string column.
See comment here: cakephp#1093 (comment)

There are no tests in phinx that prove what I've changed hasn't broken anything, and I'm not about to start writing all the test cases to prove this works.
Maybe I have indeed broken some weird implementation detail that this regex was intended to target... oh well.
