Restart dependent on working directory

[rebucci]

Job will only restart if command is issued from the job directory. If the restart is given from any other directory, the job will not run. Print statements upon attempted restart do not indicate anything is wrong. process.err shows
lockfile.LockFailed: failed to create [path]/lobster.pid

Example directories:
lobster job in /tmpscratch/users/username/batch_job_1
(failed) restart from parent directory /tmpscratch/users/username with command
lobster process batch_job_1/
(succcessful) restart from job directory /tmpscratch/users/username/batch_job_1 with command
lobster process .
