Remove un-necessary check.

[ionelmc]

Ref #48.

[georgeyk]

@ionelmc What do you think about remove this check too https://github.com/ionelmc/python-redis-lock/blob/remove-unnecessary-held-check/src/redis_lock/__init__.py#L161 ?

It opens the possibility to use a fake/dummy redis server implementation1 to write unittests without a real redis instance.

[ionelmc]

@georgeyk Hmm, we could remove it. Do you need that removal for your own test suite or something like that?

[georgeyk]

@ionelmc yes, I think fakeredis might work with python-redis-lock.

I'm not testing the lock itself, but the code that is executed with the lock.
