Using Pluggable Transports on tor master is broken
While testing a patch for #21753 (moved) I realized that PTs in general are currently broken with tor master resulting into output like
CMETHOD obfs2 socks5 127.0.0.1:41925 CMETHOD obfs3 socks5 127.0.0.1:41299 CMETHOD obfs4 socks5 127.0.0.1:34025 CMETHOD scramblesuit socks5 127.0.0.1:35225 CMETHODS DONE'. We only support version '1' Mar 16 13:03:05.000 [warn] Managed proxy at './TorBrowser/Tor/PluggableTransports/obfs4proxy' failed the configuration protocol and will be destroyed.
if started from Tor Browser.
Bisecting reveals that this got introduced with 6e78ede73f190f3aaf91623a131a20cf031aad7e which fixed #21654 (moved).
