Gets the localpart of the next generated user ID.
Generated user IDs are integers, and we aim for them to be as small as
we can. Unfortunately, it's possible some of them are already taken by
existing users, and there may be gaps in the already taken range. This
function returns the start of the first allocatable gap. This is to
avoid the case of ID 1000 being pre-allocated and starting at 1001 while
0-999 are available.
Generated user IDs are integers, so we find the largest integer user ID
already taken and return that plus one.
