Refs #7732 Changed LoadLotsOfFiles System Test

The changes to LoadAscii highlighted a problem with LoadLotsOfFiles where it was also loading .cal files when it shouldn't.

Added a blanket ban on .cal files and changed the regex search to be case insensitive.
Re #8338. Fix rarely-run system test.

The property type was changed to boolean in #8266.
Refs #8337 Add system test to check this use case.
Refs #7732 added .detcal to banned Regex in LoadLotsOfFiles

Another file that shouldn't be loaded was found, added .detcal to the banned list.

Re-added the .cal blanket ban after a merge from master overwrote it.

Refs #7732 adding a setting to HFIRTestsAPIv2 to see if it cleans up the mess.

Added the NoSaveIq() setting to the reductions in HFIRTestsAPIv2 to see it that stops it leaving fiels around. Not totally sure if this will work as i can't see if the test requires those files or not.
