fix: The XBlock should work even when max_attempts is null

[xitij2000]

Overview

This change allows the XBlock to continue working in cases where max_attempts is set to null. Currently Studio and LMS will throw an error in such a case due to a number of places where max_attempts is compared to count_attempts without testing for None first.

Test Instructions

• Set up this XBlock in a course
• Set the max_attempts in course advanced setting to 1, save, and then set it to null and save
• Test that the XBlock is working

TODO

• Compile static assets
• Lint all files
• Pass all tests
• Bump the version number in setup.py
• Attach screenshots?
• Code Reviewer 1:
• Code Reviewer 2:
• Submit PR against edx-platform to bump the version
• Upload to PyPi

Is this good to merge?

[mphilbrick211]

@openedx/2u-arbi-bom hi there! is someone able to take a look at this for us?

[mphilbrick211]

Once someone assigns themselves for review, we can resolve conflicts.

[xitij2000]

@itsjeyd @mphilbrick211 Just checking on this, how can we push this forward?

[itsjeyd]

@xitij2000 @mphilbrick211 It looks like arbi-bom was reviewing this earlier: #155 (review). How about re-requesting a review from awais786?

[xitij2000]

@awais786 Could you have another look at this PR since you reviewed it a while back?

[xitij2000]

@itsjeyd The PR has already been reviewed and approved by him, it just needs a quick review and approval from someone with merge rights as well.

[itsjeyd]

@xitij2000 Ah right, I was assuming that awais786 would have merge rights, but perhaps that's not the case. Since this repo is unmaintained, you could try pinging @openedx/axim-engineering if needed.

@xitij2000 I don't have merging rights. Also few jobs are failing in this PR.
