Use proper field separator for parsing available CLRs

[junpataleta]

The list of available CLRers in the $available variable are space-separated. So the internal field separator should be set to space instead of comma.

Plus, there is a minor fix for empty-checking the $availableCLR.

To test this fix:

1. Clone the repo.
2. Include tracker_automations/component_leads_integration_mover/lib.sh. (We just want to include the trimstring() function.)

source path/to/tracker_automations/component_leads_integration_mover/lib.sh

3. Copy and paste the following script:

available="amaia tusefomal"
# This is the code snippet containing the fix.
availableProfiles=()
IFS=' ' read -r -a availableCLRs <<<"$available"
for availableCLR in "${availableCLRs[@]}"; do
    availableCLR=$(trimstring "$availableCLR")
    if [[ -z ${availableCLR} ]]; then
        continue
    fi
    availableProfiles+=("[~${availableCLR}]")
done
outcomedesc=$(IFS=, ; echo "Sending to CLR, there are available reviewers for the issue: ${availableProfiles[*]}")
# Check the value for outcomedesc.
echo $outcomedesc

4. Confirm you see Sending to CLR, there are available reviewers for the issue: [~amaia],[~tusefomal]

Thanks, Jun
The fix looks right to me.
I have tested and it works as expected
