98-source-repositories tries to return from script

In 8b2325118ff8d3334d51d86d293962acc8dd0962 we added a line
so that 98-source-repositories tries to return from the top
level script (not from within a function).

Also, remove the return 1 within the function as well
because we just want to continue in these cases.
