reFind() and reFindNoCase() do not extract regular expression capture groups as subexpressions

Description

There is a behaviour difference between Lucee and Adobe ColdFusion 2016 & 2018, when using reFindNoCase() and reFind() with the returnsubexpressions argument to return capture groups (inside brackets) within the regular expression.

Under CF2016 and CF2018 the returned MATCH array contains only the matched capture group text in positions 2+.

However under Lucee the returned MATCH array contains a complete copy of the original string.

Sample image attached of actual versus expected results.

This issue was fixed in the lucee version 5.3.8.80-SNAPSHOT onwards. And also I added a fixed version.

I've added a test case for this ticket & confirmed the issue happened on lucee as per reporter's description in this ticket. The output for ACF & lucee differs. ACF returns two different matches but lucee returns two matches with same data.
