* CA-280287: Fix the null reference exception on the Import wizard
- Added a check so that we don't attempting to show the license warning if the wizard is open without a preselected host/pool.
- The license warning is now updated whenever the host selection changes; plus, we are not attempting to show it if the wizard is open without a preselected host/pool.
- Also a minor refactoring in the GlobalSelectHost page to fix this issue: when the wizard is open with a pre-selected host, we pass this to the page by assigning SelectedHost property, which in turn sets the m_selectedHost. The getter for SelectedHost resets m_selectedHost to the selected item in the host list. If the getter is used before the host list selection is updated, then the desired pre-selection is lost, because m_selectedHost is reset to null.
