[Editor] Fixed issue where editor mods did not get removed

[shoushou1106]

This error happens occasionally, the probability is very small but I encountered it(at 1.0.6.2).
I'm a new programmer, my English is not good, if i don't do well just ignore it, sorry for bothering.
Also, please open for issue, users don’t know how to report bugs at all

i just think itd be better to check for editor mods when launching and just delete them, so like 1-2 lines of code total

u would still need to delete the mods.json, since that stores the names of the prev mods, and if those are the same for some reason it will not regenerate

i think it would be better to delete the mods.json file in the editor than adding this boolean to the run method

OK, I did it both
Also fix a little UI bug in PrelaunchWindow2.xaml.cs

@Dyvinia pls look over this again, is the issue u mentioned fixed?

[shoushou1106]

there still needs to be modPaths.Add() for any other mods

uh, is there still any problem with it?
