fourchan: fix "Invalid server response" error when getting captcha

[N3-M3-S1S]

Looks like 4chan doesn't use 4channel host anymore and all sys calls use 4chan host now. This commit fixes "Invalid server response" error when getting captcha.

I tested methods that use createSysUri except onSendDeletePosts and everything seems to work fine, but more changes related to safe/unsafe boards may be needed (e.g. 4chan/4channel pass cookies handling).

Do we know when a new release will be made with this fix? Passcode posting is broken atm (same error), I suspect this change fixes it.

@desertkun I was now able to test the changes on my emulators and... strange results. It seems like everything works well for me both with and without the #71 fix... I also can’t confirm how massively the module is currently failing for everyone

For now, let's make a hotfix including changes #71 and #72 (without suggestions)

I hope the new version will fix the posting issues can you give me an answer later, is the problem fixed in the new version?

Did the update not have a distinct version? I have reinstalled it to latest and now can post just fine.

@desertkun the current one should be 1.1 Dashchan does not allow downgrades using the update system, the user will have to manually download versions from Github
