[DRE-maint] Bug#970782: ruby-bootstrap-switch-rails: 3.3.4 version is broken, downgrade to 3.3.3

[Pirate Praveen]

Package: ruby-bootstrap-switch-rails
Version: 3.3.4-1
Severity: grave
Control: forwarded -1 
https://github.com/Bttstrp/bootstrap-switch/issues/691

It does not seem to be fixed in 3.3.5 as well 
(https://github.com/diaspora/diaspora/pull/8149)

So we need to downgrade it to 3.3.3 which works.
