fix: Fix NoSuchMethodError for waterfall ~559

[TheXorog]

One of the updates in the last month or so changed the behavior of Kick.getMessage() to return a BaseComponent instead of a string, throwing a NoSuchMethodError when kicked.

This PR fixes said issue, updates dependencies and bumps the version to 1.6.12.

Also as a side-note: I am quite new to java, feel free to change anything you do not like or let me know if i need to change something.
