Bug 481219 - Validate container name in "Image Run" wizard

Raise an error message when a container with the same name exists.

Also added checks to avoid NPE when initializing ContainerInfo and
ImageInfo
Refactored some SWT utility classes used to setup the mock connection
  and moved some reusable blocks in JUnit rules.
