[FIX] web_editor: test equality of stripped values in updateValue

Since
https://github.com/odoo/odoo/commit/1b8d663cdccced35fd294ef3481aa7ce294880f0,
in `updateValue`, the `value` and `lastValue` could have different
`data-last-history-steps` and still be the same value.

This commit fixes the method to compare the values stripped of their
history ids.
