[Vue warn]: Error in render: "TypeError: Cannot read property 'template' of null"

[sandro78]

Subject of the issue

Undesired errors at console during tests run:

[Vue warn]: Error in render: "TypeError: Cannot read property 'template' of null"

Steps to reproduce

Was faced with above issue and found place at code which rises it:

function isComponentOptions(c) {
return typeof c === 'object' && (c.template || c.render)
}

In fact typeof null in JS also returns 'object' - have you expected this guys?)))

Expected behaviour

Suggest to change this place in way:

return !!c && typeof c === 'object' && (c.template || c.render)

Actual behaviour

Tons of errors at console like:
[Vue warn]: Error in render: "TypeError: Cannot read property 'template' of null"

Possible Solution

Haven't found workaround yet.
