gopls/internal/telemetry/cmd/stacks: fix two bugs
1. There were three early returns in the frame -> URL computation, though it was hard to see, and their formatting logic differed. This CL factors them, extracting the frameURL function. 2. When git clone fails (e.g. due to no SSO cert), we failed to clean up the empty dir, causing a persistently stuck failure state. Now we attempt to clean up the directory. (This won't help when the program is terminated from without.)
