iOS: Unable to create channel name of 2 byte characters

Description

Original report: https://forum.mattermost.org/t/i-want-to-create-channel-name-of-2-byte-character-in-application-version/6809

When the user specifies the channel name with 2-byte characters, it is noted with red letters “Name must be lowercase alphanumeric characters of two or more letters”.

Currently it is once created in alphabetic characters and modified to 2-byte characters after channel generation.

2-byte characters can be used with PC version, PC web browser, smartphone web browser without problem.

Mattermost 5.8.0, iOS apps 1.16.1, iOS 12.1.4

Jesse: We're either not enforcing the length consistently for multi-byte characters (e.g. between creation and rename), or we're incorrectly applying it at creation time.

QA Test Steps

1. Go to create a channel on the RN apps 2. Enter some non-latin characters as the name (e.g. 熊本) 3. Click create Expected: Channel is created
