beforeMessageBodyTransformed plugin hooks (and others) are not respecting async/await

Describe the bug
beforeMessageBodyTransformed plugin hooks (and others) are not respecting async/await

To Reproduce
Steps to reproduce the behavior:
_converse.api.listen.on('beforeMessageBodyTransformed', async (text, view) => {
console.log("beforeMessageBodyTransformed");
await something(text); // This await doesn't work, because beforeMessageBodyTransformed returns immedietly!
});

Expected behavior
beforeMessageBodyTransformed should wait untill await something(text) finishes before starting afterMessageBodyTransformed

Screenshots
None

Environment (please complete the following information):

• Desktop or Mobile? Affects all
• Browser [e.g. Chrome, Firefox] Affects all
• Converse.js version [e.g. 4.2.0] Latest

Additional context
None

!!! CAUSE + HOW TO FIX !!!
The cause of the bug is a capitalization error in rich-text.js.
await api.trigger('beforeMessageBodyTransformed', this, { 'Synchronous': true }); should be await api.trigger('beforeMessageBodyTransformed', this, { 'synchronous': true });
synchronous not Synchronous!

I think this affects several plugin hooks, not just this one i've found, it might be worth doing a regex to find all instances of this bug.

Thanks!

FYI i've found it in 5 places - chatBoxInitialized, messageInitialized, chatRoomInitialized, rosterContactInitialized, afterMessageBodyTransformed
