Clear the active session on delete_current_dir_session

[doongjohn]

This will make autosave_only_in_session=true not save a previously deleted session on exit when it's deleted via delete_current_dir_session.

But we already doing it here:

neovim-session-manager/lua/session_manager/utils.lua

Lines 102 to 104 in 35c154a

	if filename == utils.active_session_filename then
	utils.active_session_filename = nil
	end

This is strange... because without my modification the session is still saved on exit.

[Shatur]

Shouldn't be the case, we call utils.delete_session(session).

[doongjohn]

I guess utils.delete_session expects string so
filename == utils.active_session_filename
this is comparing session filename object and string?

[doongjohn]

I've updated the code. It's working for me.

Ah, yes, looks like a bug!
