Socket is not closed after running IsInstalledCommand

[verakruhliakova]

Calling device.isInstalled(pkg) leads to a socket leak.

If application calls this command in a loop, eventually app crashes with EMFILE: too many open files.

Checking occupied sockets shows that they hang in CLOSED state, but never actually released by the machine.

Environment:
Node: v20.11.0
OS: MacOS 12.6.5

The reason to this issue is that command calls parser.readAscii() and never finishes reading the socket stream, which prevents socket from being closed.
