Rationale

If you use use_displaced = true in your outputter and there is no displaced problem, the code crashes.

Description

To reproduce, run this input file:

[Mesh]
  type = GeneratedMesh
  dim = 1
  nx = 2
[]

[AuxVariables]
  [./a]
  [../]
[]

[AuxKernels]
  [./a_ak]
    type = ConstantAux
    variable = a
    value = 1.
    execute_on = initial
  [../]
[]

[Problem]
  solve = false
[]

[Executioner]
  type = Steady
[]

[Outputs]
  [./exodus]
    type = Exodus
    use_displaced = true
  [../]
[]

Impact

Needs to warn the user and quit, crashing is ridiculous.

Fallback to non displaced problem if none is present
611db89 
If users required output on displaced mesh via 'use_displaced = true',
but there is no displaced problem, MOOSE should use the non-displaced
problem instead and warn the user about this fact.
