The `cloudbuildResourcesFromBuildLog()` function from the internal GCP package could cause panic while parsing Build job log which failed early and didn't create any Compute Engine resources. The function relied on the `Regexp.FindStringSubmatch()` method to always return a match while being used on the build log. Accessing a member of a nil slice would cause a panic in `osbuild-worker`, such as: Stack trace of thread 185316: \#0 0x0000564e5393b5e1 runtime.raise (osbuild-worker) \#1 0x0000564e5391fa1e runtime.sigfwdgo (osbuild-worker) \#2 0x0000564e5391e354 runtime.sigtrampgo (osbuild-worker) \#3 0x0000564e5393b953 runtime.sigtramp (osbuild-worker) \#4 0x00007f37e98e3b20 __restore_rt (libpthread.so.0) \#5 0x0000564e5393b5e1 runtime.raise (osbuild-worker) \#6 0x0000564e5391f5ea runtime.crash (osbuild-worker) \#7 0x0000564e53909306 runtime.fatalpanic (osbuild-worker) \#8 0x0000564e53908ca1 runtime.gopanic (osbuild-worker) \#9 0x0000564e53906b65 runtime.goPanicIndex (osbuild-worker) \#10 0x0000564e5420b36e github.com/osbuild/osbuild-composer/internal/cloud/gcp.cloudbuildResourcesFromBuildLog (osbuild-worker) \#11 0x0000564e54209ebb github.com/osbuild/osbuild-composer/internal/cloud/gcp.(*GCP).CloudbuildBuildCleanup (osbuild-worker) \#12 0x0000564e54b05a9b main.(*OSBuildJobImpl).Run (osbuild-worker) \#13 0x0000564e54b08854 main.main (osbuild-worker) \#14 0x0000564e5390b722 runtime.main (osbuild-worker) \#15 0x0000564e53939a11 runtime.goexit (osbuild-worker) Add a unit test testing this scenario.

Specifically the `storageCacheDir.bucket` may be an empty string and thus won't exist.
