[fuchsia_roller] Truncate roll URL

Showing the full Gerrit CL ID in URLs is ugly and overflows the tree
status box that shows up in Gerrit, so we truncate the ID to 12
characters (including the leading 'I') when constructing a URL.

To test this, I had to change the mock change ID constructed in
auto_roller/api.py, which is why there are so many expectation file
diffs.
