[ModelManager] Merging find parameters

Hi,

when using getRelated() method in a model with non-trivial find paramaters, for example while using OR in a condition, it behaves strangely and bad query is generated for me.

I think is an error on these lines:
https://github.com/phalcon/cphalcon/blob/master/phalcon/mvc/model/manager.zep#L1130
https://github.com/phalcon/cphalcon/blob/master/phalcon/mvc/model/manager.zep#L1151

and I think that $value should be wrapped inside brackets as well. Because related records have this implicit equality condition on foreign key columns.

But when using OR keyword inside parameters when calling getRelated() instead of condition like this:

[
    'conditions' => '<foreign-key-cond> AND (<cond1> OR <cond2>)'
]

is generated only this

[
    'conditions' => '<foreign-key-cond> AND <cond1> OR <cond2>'
]

Which is obviously wrong. This can be fixed manually by including the brackets in the condition:

return $this->getRelated('relatedAlias', [
    'conditions' => '(<cond1> OR <cond2>)' // without brackets it doesn't work
]);

But from the users point of the view it should be better to do it automatically. Because users do not need to know about any of the implicit conditions.

You can create PR with fix for it if you need it now.

OK, so here is the PR for review #11990
