syntax: Reset query cursor byte range for textobjects

`InactiveQueryCursor::new` might reuse a query cursor from a
thread-local cache if one is available, rather than create a new cursor.
Currently tree-house does not reset cached cursors back to defaults
(i.e. byte range and match limit). For now we can patch around this here
but eventually this should be fixed in `tree-house` upstream. Then this
patch can be reverted.

In practice this caused textobjects like `]f` to get "stuck" trying to
move to the next function if it was out of the current view. This is
because the highlight query cursor sets the range of the cursor to the
current viewport. We can reset the byte range to defaults to fix the
textobject behavior.
