Remove text props from callback args in erc-button

* lisp/erc/erc-button.el (erc-button-add-buttons-1): Remove text
properties from strings stored in `erc-data' and passed to
`erc-callback'
(both text properties themselves) (bug#49704).  This reduces
memory usage in erc buffers (which are long-lived and can become
very large).
