Disabling AppStartup silently breaks the library

[Nek-12]

About this issue

1. Follow Official Google guide on workmanager
2. The guide says "If you do not use AppStartup in your project, you can disable it" Note: I also use Koin for DI and it has its own custom init mechanism for workmanager, which is why I disabled AppStartup.
3. Disable AppStartup in the manifest
4. Iconics no longer resolves icons for any of the default font typefaces when trying to use their string representation e.g. "gmr_near_me", but works when using .getIcon() Side effects:
   • Resolving fails silently, no warnings are given because icon(String) extension function uses ?.let { } which ignores unresolved typefaces and only reports icon resolution errors
   • No warnings or error are given that appStartup is disabled.

Thank you very much for the report @Nek-12 I'll add a note in the README to highlight the usage of jetpack startup library

@mikepenz Why have you decided to ignore font resolution errors in the code? In this file on line 42 you do not give a warning. Is that intended and if yes, what's the reason behind?

@Nek-12 that was mainly a historic matter, adding a log for the next release.
