Incorrect tooltip message on Settings tab

[Julia Aranovich]

Steps to reproduce:
1. create default env + Ironic service enabled
2. add Ironic node(s)
3. go to Settings tab and see that Ironic service setting is disabled.

Expected result: the setting tooltip text says "Environment contains Ironic nodes"
Actual result: "Environment containsIronic nodes" (no gap between words)
