 flyway#754 fix bug on quote together with comment
Extended the maven-plugin so after migration it records the current DB version in the "flyway.current" property.
This can later be used in maven builds that needs to know this version.

Also extended maven-plugin-largetest to test the "executions" section of the plugin.
