Test: Use Sinon.js instead of FakeDate

[rxaviers]

Note: lolex's 3664eb8d90dd1d6fa04a098f77b77b19a6bb5850 sha corresponds
to its 1.1.0 npm version (version is present on npm, but not git tagged
accordingly).

Ref #374
Fixes #382

Have you verified that sinon and its dependencies use AMD properly?

[rxaviers]

I had and it said it would.

[jzaefferer]

Is there a ticket for getting that tag-free commit tagged properly?

[rxaviers]

I've noticed it's tagged as 1.1.10 in the repo. But, as 1.1.0 in npm.

[jzaefferer]

Looks like the latest version, 1.2.1, is tagged and published, can you use that?

[rxaviers]

Can we? Good question. Sinon.js latest release is 1.12.2, which uses lolex@1.1.0 (i.e., 1.1.10 or 3664eb). I would use lolex@1.2.1 when there's a newer Sinon.js release explicitly telling us to use it.

Seems easy enough to test.

[cjohansen]

Feel free to use Lolex 1.2.1. Sinon master is using it with no problems.

[rxaviers]

Thanks

Closing. Anyone, feel free to continue my work.
