[actions] Fix `get()`, `thingActions` & dynamic export of found actions

[florian-h05]

Fixes #164. Caused by #148.

Fixes

• actions.get() not working
• actions.thingActions() not working
• Dynamic exports not working
• Removed Pushsafer example from README as the Pushsafer binding does not dynamically export to the actionService.

Test

I’ve verified that get(), thingActions() and the dynamic exports are working now.

@basvanh Can you please test this fix? Just run npm install git+https://github.com/florian-h05/openhab-js.git#fix-actions-get inside the $OPENHAB_CONF/automation/js folder.

@digitaldan The creator of the issue also verified that it’s working, so I’ll merge.
