chore(backends): change logic used to detect if the user accessed via a numbered backend or main domain
All checks were successful
Invidious CI / build (push) Successful in 6m4s
Details

Browse source 
Numbered backends will only work if the domain has a number at the end, for example:

inv1.nadeko.net will redirect to backend 1
inv2.nadeko.net will redirect to backend 2
2inv.nadeko.net will use cookies
nadeko1.net will redirect to backend 1

The number of the backend in the domain should be always on the end of it to be able to use numbered backends.
