object names ending with space cause problems

[moreamazingnick]

Describe the bug

object names ending with space cause problems.
I know it is a bad idea to use spaces at the end of object names but it was discovered by a "copy and paste"-create-service-task

To Reproduce

1. create an service with e.g "test "
2. add service as a node
3. store

Expected behavior

Services should be displayed correctly for all valid icinga object names
