CI dashboard tests should garbage-collect earlier.

Description of the change

Still seeing some dashboard test runs on CI failing when workers get close to 1Gb (see details in comment). Forgot that we probably need to leave some memory for other processes, so updating to cause GC when a worker has 512Mb old mem.

Benefits

Hopefully more stable CI.
