Rule `typecheck-object` is wrongly failed for simple comparing with 'object'

Rule `typecheck-object` is wrongly failed for simple comparing with 'object' string

```javascript
var variable = 'object';
return variable === 'object'
```

Same issue with other `typecheck-*` rules

I have opened the [same issue](https://github.com/Gillespie59/eslint-plugin-angular/issues/444) some time ago but looks like it was wrongly interpreted.
As for me, tests added in [commit](https://github.com/Gillespie59/eslint-plugin-angular/commit/092ce8cca802c817140c816b3fdccdf40908c4b2) shouldn't show errors.
I think it is no sense to show error when `typeof` is not used before the variable name. In the project where I work, we have our own business "types" which are described by some object's property. And because of this rule we need put /*eslint angular/typecheck-object: 0*/ in a lot of places
Or at least there should be an option to disable such restrict check of type.
