INCORRECT WORKAROUND for cordova-sqlite-storage BUG 666 in this plugin version

[brodycj]

INCORRECT WORKAROUND (apply ROLLBACK when opening database in a new web page) for storesafe/cordova-sqlite-storage#666 is included by this plugin version due to possible timing issue.

New workaround solution to storesafe/cordova-sqlite-storage#666 is to attempt to close database before opening. Unfortunately this new workaround solution may be problematic in case the same native database handle is accessed from a combination of main and worker threads.

Probably the best solution would be parallel database access handles as discussed in #3 (comment).
