Issue with url function replacement

Description

Django-upgrade changes this kind of url functions:
url(r"^foo", my_view)

with these path functions:
path("foo", my_view)

However, the automated change made by the library is not backwards compatible. The initial code allowed all paths such as foos, footest etc., whereas the upgraded code only allows foo (the missing $ in the first example being the problem).

For this use-case, a backwards compatible solution would have been this:
re_path(r"^foo", my_view)

I would be glad to offer any help needed if you would take this issue into consideration.

I'm surprised that url(r"^/foo", ...) even matches anything. it doesn't seem to work in my local testing at all.

The Django docs state that there's no need to add a leading slash and I haven't found a single example containing a leading slash. I'm sure it works on your end but it's still strange.

Yeah my bad, that was not a good example, let's forget about those leading slashes, I have removed them in the issue to avoid the confusion.

Fixed in #133
