After applying new exec agent some commands may be invalid

[musienko-maxim]

Reproduction Steps:

1. We used only shell commands before the exec agent. But exec agent bash command. In this way many commands that was written early may not work.
   It may create many unexpected errors for users of the Codenvy.
   For example: echo -e '123' > ~/test.txt
   Expected behavior:
   should be created file with content like: 123
   Observed behavior:
   we have file with content like: -e 123

Go to the nigtly5 or nigtly server and create workspace from java stack for example.
