Call Service doesn't work with spaces in comma-delimited entity ID list

[rogersmj]

Describe the bug
If there are spaces between the comma-delimited list of Entity IDs in the Call Service node, only the first item in the list is acted upon.

To Reproduce
Steps to reproduce the behavior:

1. Create a Call Service node. Set Domain: homeassistant, Service: turn_off
2. Put multiple items in the Entity ID list, with a space between each (which is what the auto-complete functionality does). For example, group.kitchen_lights, light.foyer_light, group.basement_lights, group.exterior_lights
3. Run the node. Observe that only the first item in the list turns off.

If I delete the spaces between the items, so that it reads:

group.kitchen_lights,light.foyer_light,group.basement_lights,group.exterior_lights

It works.

Expected behavior
All items in the Entity ID list would be included in the service call.

Environment (please complete the following information):

• Node Red Version: [e.g. 0.19.5] 1.0.2
• Node.js Version: [e.g. 8.12.0] not sure
• NR Home Assistant Plugin Version: [e.g. 0.5.0] 0.16.3
• Is Node Red running in Docker: [e.g. yes/no/hassio] hassio

Other (please complete the following information):
Note that the auto-complete feature for entity IDs automatically puts spaces between the entities. This caused a lot of confusion, and it took awhile to hunt down why my Call Service wasn't working properly.
