Remove stringify tests

[kislaykishore]

Description

These tests attempt to test the behavior of stringify method but in reality don't serve much purpose for the following reasons:

• This test doesn't really test whether the util.Stringify was called.
• They test the behavior of util.Stringify but there are tests in util package that do that here.
• They are usually a nuisance while adding flags as the tests break on flag addition.

Link to the issue in case of a bug fix.
