Added URL encode to HTTP GET to check if target remote job is
parameterized. Previously, a remote job with spaces in the name would
cause a failure while attempting to check for job parameters. This
caused each build trigger step to retry the parameterization check 5
times and then swallow the resulting AbortException.
