Unexpected "Source > Format" Context Menu in Project Explorer

[BeckerWdf]

In our Product we see unexpected "Source > Format" context menu entries in the project explorer basically everywhere.

See:

But this can also be seen e.g. with plain JDT.

This is confusing because there is already a "Source" context menu entry that has a "Format" entry in it's sub-menu.

The cause is #364. This part in the plugin.xml looks a bit too broad for me:

      <menuContribution locationURI="popup:org.eclipse.ui.popup.any?endof=group.generate">
         <menu label="Source" mnemonic="S" >
            <command commandId="org.eclipse.lsp4e.formatfile">
               <visibleWhen>
                  <iterate>
                     <or>
                         <adapt type="org.eclipse.core.resources.IFile">
                            <test property="org.eclipse.lsp4e.hasLanguageServer" />
                         </adapt>
                         <adapt type="org.eclipse.core.resources.IFolder" />
                         <adapt type="org.eclipse.core.resources.IProject" />
                     </or>
                  </iterate>
               </visibleWhen>
            </command>
         </menu>
      </menuContribution>

Can we improve this?
