Use of deprecated env.get_version(db) in trac core

[ethan.jucovy@…]

The docstring for Environment.get_version in trac/env.py states:

        :since 1.0: deprecation warning: the `db` parameter is no

However, code in trac/env.py on trunk calls get_version(db).

The following patch removes the deprecated db argument in the function call. Trac's tests still pass after this patch is applied.
