fix(3182): fixed increment/decrement values of embeded entity

[vlapo]

Root of problem:
Current implementation of increment/decrement method for embedded property define values to update like this:

// ...
.set({
    "embedded.property": () => ...
})
// ...

But update query builder do not support define key as string with "dot notation path".

Solution:
Convert:

.set({
    "embedded.property": () => ...
})

to:

.set({
    embedded: {
         property: () => ...
    }
})

Note: Sure we can add support of "dot notation path" into set() method but right now set() method accept strongly typed argument and I think it is better keep this functionality and just update increment/decrement function as it is presented in this PR.

Fixes #3182
