fix(constant.formatter): Makes constant formatter serialize objects in a useful way

[runia1]

Description

Moq.ts is a great library but sometimes can be hard to track down test failures due to the way data objects are serialized. For example, you may get an error message that looks like:

     Error: upsert(0, [object Object]) should be called once, but was called 0 time(s)
-------------------------------------
Tracked calls:
Getter of 'upsertMany'
upsert(0, [object Object])
-------------------------------------

With this fix, the error messages will be more useful such as:

     Error: upsert(0, {'hello': 'world'}) should be called once, but was called 0 time(s)
-------------------------------------
Tracked calls:
Getter of 'upsertMany'
upsert(0, {'hello': 'world!'})
-------------------------------------
