Unchecking 'Show Left/Right Sidebar'  unchecks the dock widget from Views

PRE-REQUISITES:

• Ensure that all views are checked (Widget Box, Object Inspector, Property Editor, etc) from 'View->Views' menu
• The 'Show Left Sidebar' and 'Show Right Sidebar' are checked in 'View' menu

STEPS:

• Open Qt Creator and open some project with .ui file. (To check the View->Views menu)
• Open the .ui file to enable 'View->Views' menu
• Ensure that all views are checked (Widget Box, Object Inspector, Property Editor, etc)
• Widget Box on Left Sidebar, Object Inspector and Property Editor on Right Sidebar)
• Now uncheck 'Show Right Sidebar'
• Observe that 'Object Inspector' and 'Property Editor' gets unchecked from View->Views menu. 
• The  'Show Right Sidebar' is still enabled
• Now check 'Show Right Sidebar' .  
• Observe that  'Object Inspector' and 'Property Editor' gets checked from View->Views menu. 
• Now uncheck  'Object Inspector' and 'Property Editor'  from View->Views menu
• Observe that  'Show Right Sidebar' gets  disabled.

OBSERVED:

• Views get unchecked if the 'Show Left Sidebar' or  'Show Right Sidebar' unchecked
• When views are unchecked from 'View->Views', the 'Show Left Sidebar' or  'Show Right Sidebar' gets disabled. This is OK

EXPECTED:

• Views shouldn't get unchecked when the Left/Right Sidebar is unchecked.

Consider user sees Views as unchecked, and then in one use case he sees the Left/Right Sidebar item enabled and in another use case as disabled.  This is a bit confusing/incorrect.

NOTE:  In Qt Creator 12.0.2, the  'Show Left Sidebar' or  'Show Right Sidebar' were disabled when the designer was open. So cannot test same use case on 12.0.2
