Vdebug buffers are not closed on vdebug close

[BlackIkeEagle]

From my example:

• start vdebug with and wait for an incoming connection from xdebug
• start debugging
• found an issue, close debug with , the vdebug tab with its buffers is still open (normal behaviour)
• press again to close the tab where the debug session was run

:ls shows me the buffers 'DebuggerWatch', 'DebuggerStack' and 'DebuggerStatus' are still open.

I discovered the issue was introduced in 7ece7e5 but I've not yet pinpointed what causes the autocommands to close the buffers to be skipped.
