[WIP] Fix for numpy array equality checking bug

[ivanistheone]

This is PR is a work in progress (NOT READY TO MERGE) and contains two commits.

• The first is a whitespace only commit + reorder of imports
• The second is a partial fix of issue https://github.com/sympy/sympy-live/issues/110

When reviewing, please check only the second commit to avoid seeing lots of unrelated whitespace changes.

Note on line L333 I disabled the call to int_to_Integer to isolate the bug, but this is not the final fix, because we shouldn't change the default behaviour: int to Integer conversion is a very important part of sympy-live UX.

The underlying cause seems to be problem with int_to_Integer in upstream, see https://github.com/sympy/sympy/issues/13027
