Mocha Config: Enable Mocha Test Explorer

[TheArhaam]

Description

The repository was missing a .mocharc.js that makes it compatible with Mocha Test Explorer.

Changes made:

• Configured a mocharc.js file
• Fixed missing type assertions in the test suite for ExecutorManager, MockAdaptor, MockSwapRouter and UniswapAdaptor. The missing assertions were preventing the Test Explorer from running the tests.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

How Has This Been Tested?
