'setLocaleMessage' / 'mergeLocaleMessage' doesn't work if 'warnHtmlInMessage' is set to 'error'

vue version: 2.6.11

Reproduction Link

Steps to reproduce

Set warnHtmlInMessage: true.

Call setLocaleMessage or mergeLocaleMessage to change messages for any locale.
It doesn't matter whether messages were already set for the locale or not.

The new messages must NOT contain HTML.

What is Expected?

Messages are changed for the target locale.

What is actually happening?

setLocaleMessage or mergeLocaleMessage have no effect.

The reason is the following line of code for setLocaleMessage:

https://github.com/kazupon/vue-i18n/blob/v8.x/src/index.js#L606

and the following line for mergeLocaleMessage:

https://github.com/kazupon/vue-i18n/blob/v8.x/src/index.js#L614

Hey @vovkss
Can I grab this?
Also, since we expect the messages to be changed anyway, what's the point of having an error flag for warnHtmlInMessage?

Sure, I guess you can :)

According to the docs, 'warnHtmlInMessage' applies to dynamically loaded messages:

setLocaleMessage( locale, message )
...
If you set warn or error in the warnHtmlInMessage property, when this method is executed, it will check if HTML formatting is used for locale message.
