__repr__ implementation of multiple apply schemas double quotes instance name.

[nvmkuruc]

Description of Issue

The code gen template for multi apply schemas is this. Note that it adds single quotes around instanceName.c_str().

    return TfStringPrintf(
        "{{ libraryName[0]|upper }}{{ libraryName[1:] }}.{{ cls.className }}(%s, '%s')",
        primRepr.c_str(), instanceName.c_str());

However instanceName was constructed using TfPyRepr which already adds quotes to strings.

The fix is simple, but it will requires rerunning schema gen on all schema domains.

Steps to Reproduce

1. Run the following code snippet

>>> s = Usd.Stage.CreateInMemory()
>>> p = s.DefinePrim('/root')
>>> Usd.CollectionAPI.Apply(p, 'c')
Usd.CollectionAPI(Usd.Prim(</root>), ''c'')

Note that ''c'' has two single quotes on each side instead of one.
