Fix: Icinga environment corruption on Icinga Agent installation failure

In case the Icinga Agent could not be installed, regardless of the reason, we should not write any zone, api or other related config to the environment.

By doing so, we can corrupt the environment and make it impossible for the Icinga Agent to be installed in the future, unless we manually delete the folowing directories:

* `C:\ProgramData\icinga2`
* `C:\Program Files\ICINGA2`
* `C:\Program Files (x86)\ICINGA2` (only for x86 installations)
