Algorithm progress can get stuck at 100%

[Nick Draper]

The progress bar stays at 100%, if you click details it is empty though, so it is just the progress bar.

This script causes it reliably on my pc (win 64)

for i in range(150):
    ws2 = Load('MUSR00015190.nxs')

[Nick Draper]

Actually is takes two of these scripts running simultaneously to cause the problem, but one caused it stays for the last algorithm until restarted.

As the likelihood is lower, decreased in priority and moved back a release.

This keeps cropping up in testing and would be good to fix for this release.

Fix issue with progress reporting getting 'stuck' Refs #6437

When other threads started algorithms they messed up the assumption that the list of tracked algorithms would be empty when the last algorithm finished. The fix ensures all tracked algorithm pointers are removed when the corresponding algorithm finishes.

Tester: The problem showed itself quite effectively by either running the above script in two separate tabs simultaneously or by running the script and trying to load a file through the Load button while it is running.

The effect now should be that the progress bar has disappeared when the last algorithm has finished.

Tested with version that didn't include fix and the progress bar remains visible. Version that includes changes, the progress bar is no longer there.
