Classify multiple defect bugs at a time in the code to find bug-fixing commits

[willT97]

Following on from #1866.

When a bug is classified as a defect, it is then classified by the regression model one bug at a time in

bugbug/scripts/regressor_finder.py

Line 266 in 1a584d6

if regression_model.classify(bug)[0] == 1:

we could collect all the bugs that are classified as defect and classify them in one go.

Tested by running python -m scripts.regressor_finder bug_fixing

@aadarsh10c the first comment contains a good description of what needs to be done. You can also take a look at the recent PR by @willT97 which made a similar improvement: #2001.
