can not run single test using rt.sh

Description

can not run single test using rt.sh

To Reproduce:

1. /rt.sh -l rt.conf -n control_p8 intel -a $ACCNR
2. then failed with err.msg:
   'The -n option needs AND in quotes, i.e. -n "control_p8 intel"'
3. then tried /rt.sh -l rt.conf -n "control_p8 intel" -a $ACCNR
   run all regression tests.

Thanks for this issue Wen. I believe without the -l rt.conf it will run only that one test. But, the issue is that when the user specifies -l and -n it should run the test using that specified conf file, which is a use case that I know I haven't tested for.

@BrianCurtis-NOAA JFYI, we are always using -l and -n together under ufs-coastal without any issue. But of course, we did not sync ufs-coastal recently and I think that "control_p8 intel" usage is new. So, maybe the update in RT system break that capability. If so we might need to fix it since ufs-coastal has its own test file called as rt_coastal.conf at this point. Anyway, once i synced ufs-coastal again, I'll check and report back.

Leaving a note here that the current develop works fine running a single test with -n and without -l in a recent test on gaea at
/gpfs/f5/epic/scratch/Fernando.Andrade-maldonado/reg-test/wm/dev-test/ufs-weather-model/tests/logs/RegressionTests_gaea.log

Please ignore the error itself in the log, that's a system issue.
test was run with ./rt.sh -a epic -e -c -n "regional_spp_sppt_shum_skeb intel"

I think a fix for this has been found, as seen in issue 2244, so this can be closed once the commit is in develop.

Closing as UFS-WM PR #2241 has been merged.
