bundlerepo: raise `error.LookupError` instead of `LookupError`

I'm pretty sure that this was the intention, given `error.LookupError` is raised
a few lines above with the same arguments.

Note that PyCharm complains about `self.display_id` (and the use above this too)
being `() -> Any` instead of `bytes`, but it may be confused about the
`util.propertycache` annotation on it.

import os
import time


# work around check-code complains
#
# This is a simple log level module doing simple test related work, we can't
# import more things, and we do not need it.
environ = getattr(os, 'environ')


def _timeout_factor():
    """return the current modification to timeout"""
    default = int(environ.get('HGTEST_TIMEOUT_DEFAULT', 360))
    current = int(environ.get('HGTEST_TIMEOUT', default))
    if current == 0:
        return 1
    return current / float(default)


def wait_file(path, timeout=10):
    timeout *= _timeout_factor()
    start = time.time()
    while not os.path.exists(path):
        if timeout and time.time() - start > timeout:
            raise RuntimeError(b"timed out waiting for file: %s" % path)
        time.sleep(0.01)


def write_file(path, content=b''):
    if content:
        write_path = b'%s.tmp' % path
    else:
        write_path = path
    with open(write_path, 'wb') as f:
        f.write(content)
    if path != write_path:
        os.rename(write_path, path)
