Named view not being cleared when empty template provided

[migajek]

I'm using the named view for displaying the global menu. There are however several sub-pages where I want the menu to be hidden.
Thus the menu div has default content <div ui-view="menu"> ... some content ..</div> and the content is supposed to be overriden with empty only on those subpages where menu is hidden.
I found out however that setting en empty string as the template content does not work, instead I have to use ' ':

'named@': {template: ''} // does not work
'named@': {template: ' '} // works

The empty string is falsey. I suspect we are doing a truthy test as opposed to an undefined test.
