Ignore rule Scope should always be MultiWildcard

Upstream Quassel always uses the MultiWildcard mode for matching Ignore Rule Scope. This is for backwards-compatibility with Quassel 0.12.x and lower, where the Regular expression checkbox only applied to the rule itself, not the scope.

Quasseldroid should follow this. In IgnoreListManager.kt, it should be changed so…

-        if (isRegEx) ExpressionMatch.MatchMode.MatchRegEx

+        ExpressionMatch.MatchMode.MatchMultiWildcard,
         true
       )
     )

Regular expression should continue to affect ignoreRule itself, as before.

Thanks to #170 (closed) for bringing this issue to attention.
