fix(ios): conflicting styles in typing attributes not correctly detected (#770)

# Summary

There was a bug which you can see in the attached video below. The issue
was that when applying `codeblock` style, we apply it to a whole
paragraph, and during this process we look for conflicting styles in the
paragraph's range. The problem is, we don't look at current typing
attributes for conflicting styles, as there is a case when:

- there is no conflicting style in the given paragraph range
- there is a conflicting style in typing attributes

The implemented fix is minimal, as I didn't want to tamper with current
logic - that's why we catch that specific case with an `if`.

I've run the e2e tests, everything passes.

## Test Plan

Reproduce the bug from the attached video, play around with toggling
different styles.
