The "sComposerFilter != m_sRowSetFilter" could not influence the result.
Proof.
 The right hand-side of the || is evaluated only when m_sRowSetFilter.isEmpty()
 So the only case where the removed test could have an influence is when
 m_sRowSetFilter.isEmpty().
 However, the right hand-side of the && is evaluated only when !sComposerFilter.isEmpty().
 We have m_sRowSetFilter.isEmpty() and !sComposerFilter.isEmpty().
 In particular, (sComposerFilter != m_sRowSetFilter) is true.
Qed.
