Analyzer: Make sure right tool is shown when triggered via menu

Selecting a tool via menu while the Analyze mode is active resulted
in the wrong 'default' tool being selected when the tool finally
forces a switch to Analyze mode. This fixes it by switching to
Analyze mode first -> default tool is shown -> selected tool is shown.
