infinitepush: use the new function to determine push destination

Since 066b8d8f75b8, the push command accept multiple destination. `infinitepush`
was not aware of that. We now use the new `urlutil.get_push_paths` function to
determine the push destination, fixing the issue. This will also make future
evolution of that logic transparent for infinitepush

We still disallow push to multiple destinations if infinite push is enabled
because I don't know what this means for infinite push. However user will now
get a clear error message instead of a crash.

# A repository with the sparserevlog feature will have delta chains that
# can spread over a larger span. Sparse reading cuts these large spans into
# pieces, so that each piece isn't too big.
# Without the sparserevlog capability, reading from the repository could use
# huge amounts of memory, because the whole span would be read at once,
# including all the intermediate revisions that aren't pertinent for the chain.
# This is why once a repository has enabled sparse-read, it becomes required.
