In Python 2, hasattr swallows *any* exception raised during the
access. In Python 3, it only swallows AttributeError.
Accessing an attribute on an unbound threadlocal proxy raises
RuntimeError, while running test_ir_http_mimetype ``request`` is
unbound, in Python 2 ``hasattr`` would return ``False`` on an unbound
threadlocal, in Python 3 it lets ``RuntimeError`` pass through blowing
up the test.
Fix this by just checking if the threadlocal is bound by using it as a
boolean…
