Remove invalid test ctkResizableFrameTest1

Commit b941732b1 added both widget `ctkExpandableWidget` and test
`ctkResizableFrameTest1`. Then commit 6f64321 added test `ctkExpandableWidgetTest1`

This commit removes invocation `ctkResizableFrameTest1` since it isn't
associated with any implemented test.

See #352
