[BUG] Unsuccessful exit when using `wash up --disable-wadm`

[Iceber]

Describe the bug
A clear and concise description of what the bug is.

I use wash up --disable-wadm to start washcloud.
when I use ctrl-c to exit the program, it fails because --disable-wadm does not create the wadm process and the wadm.pid file, and removing the pidfile on exit will cause it to fail

To Reproduce
Steps to reproduce the behavior:

1. Run command 'wash up --disable-wadm'
2. . Run other command 'ctrl-c'
3. . See error

^C>>> ⢀⠀
