Bug summary

When we delete a localvar with buffer_autoset (that we have added with buffer_autoset before) the localvar is still there until we close and reopen the buffer

Steps to reproduce

1. /buffer_autoset add core.weechat localvar_set_testing 1
2. /buffer localvar (on core.weechat)
3. /buffer_autoset del core.weechat.localvar_set_testing
4. /buffer localvar (on core.weechat)

Current behavior

The localvar is still there until we close and reopen the buffer

Expected behavior

The localvar should be gone
