When the project is specified in the install script, the behavior is incorrect.
E.g.

./install_ocp.sh --datavirt -p syndesis

Firstly, the script wants to create a secret with credentials.
After that it clean project/namespace. (see image installer.png)
This action delete the secret created before so operator image cannot be pulled. (see image Soperator.png)

Order of these steps should be changed for option --project (-p)
