Crashes if /system is not already mounted

[Shadow53]

Attempting to run tingle from TWRP without /system mounted (the default behavior, it seems) results in this crash message:

Traceback (most recent call last):
  File "main.py", line 396, in <module>
    brew_input_file(mode, chosen_one)
  File "main.py", line 263, in brew_input_file
    output = subprocess.check_output([DEPS_PATH["adb"], "-s", chosen_one, "pull", "/system/framework/framework.jar", "."], stderr=subprocess.STDOUT)
  File "/usr/lib/python3.5/subprocess.py", line 626, in check_output
    **kwargs).stdout
  File "/usr/lib/python3.5/subprocess.py", line 708, in run
    output=stdout, stderr=stderr)
subprocess.CalledProcessError: Command '['/usr/bin/adb', '-s', 'ZX1G22M5TH', 'pull', '/system/framework/framework.jar', '.']' returned non-zero exit status 1

Perhaps including a couple of adb commands to check if /system is mounted at all before pulling the framework.jar?

On a side note, I saw that Tingle correctly remounts /system as rw if it was mounted ro, but I got this message. Everything worked out and the system got patched, but the DEBUG message is confusing: *\ Remounting /system... DEBUG: remount of vendor failed: Success remount failed

The thing of unmounted /system is a know issue, I will fix it but I have had no time yet.

The debug message just show what the adb command report (it isn't a message written by me), the problem of confusing message is a problem of Android itself (not sure if it is in adb for the pc or in the recovery code).

It should be fixed, please try the latest version and report back.
