IBX-8602: Always load root location using sudo in the ContentTreeController

[barw4]

🎫 Issue	IBX-8602

Description:

The issue stems from the fact that we are loading the location of ID = 1. If a user has some limitations on locations or subtrees, even if he selected all of them he won't be able to load the root location of ID = 1. Another limitation is that we cannot select the root location in limitations.

The following PR proposes to always load the root location using sudo and the rest of them using a standard call with policies validation.

If we won't go with this solution we have probably one option and that is to load multiple tree roots in the frontend simultaneously, it probably requires a lot of work.

I am unsure about loading root node without permissions. Specifically, I think it is also possible to declare root locations for site accesses.

I am almost certain that's not gonna hold due to security.
