refactor tab modification by components

@polesye please take a look

I'd prefer to name it so is_advanced_module_present.

Looks like _a_component_is_present and _component_value_true get the same arguments, but argument's names differ. I'd like to see the same names in both function. For example, components.

[tymofij]

let's settle on is_advanced_component_present - they are called components all over

[polesye]

I'd prefer to name it so is_field_value_true or is_truthy.

[polesye]

Do we really need to pass the request as an argument or we can pass request.json instead?

[tymofij]

is_field_value_true it is

[polesye]

👍 once tests pass and small comments will be addressed.
