fix: Scope Issue with the 'entry' variable when looking up remote images and tests additions

[3droj7]

Related: #9177

Description
The variable "entry" was not overridden before triggering the lookupRemote method.
The reason is because the entry variable was redeclared within an if block, resulting in a new, locally scoped variable. This redeclaration prevented the updates made to entry within this block from being reflected outside of it.

The bug was introduced in my last PR (9181)... I had no idea that in go, the "if" statement can define a whole new scope

I've also added some tests, so it would test the scenario where we have tags in the remote which shouldn't be built and also fixed another test where it uses missingPull functionality on the remote
