Pre-launch hook: Use addon name instead of host name as settings key

Changelog Description

Use explicit addon name instead of host name to get addon settings.

Additional review information

Because addon name and host name are same it did work, but code-wise is confusing. It should look explicitly for addon name, not host name (confusing those who use other addons as example).

Testing notes:

1. Validate the reasoning of the change.
2. Nothing really changed technically.

Thank you for the suggestion @BrookRaindle. Yes it seems for some that it is confusing yet this is in consistency with other addon implementations. There might be a reason for this - I can only guess that perhaps we might need to change the host name later and this way we will not need to do replacements on multiple lines.

Why is this closed @jakubjezek001

I'm pretty sure @iLLiCiTiT would say this is the correct fix? Since it was also fixed for fusion for example.

[iLLiCiTiT]

It is indeed correct fix. It should not use host_name, even if the value is same as addon name.
