OP2: modal CBAR not written written with analysis code = 2

[SteveDoyle2]

cbar_stress[(1, 1, 1, 0, 0, '', '')] type=RealBarStressArray nelements=4 data: [1, ntotal, 15] where 15=[s1a, s2a, s3a, s4a, axial, smaxa, smina, MS_tension, s1b, s2b, s3b, s4b, smaxb, sminb, MS_compression] data.shape = (4, 4, 15) element.shape = (4,) element type: CBAR-34-34 sort1 lsdvmns = [1 2 3 4]; dtype=int32

The code is as follows:

(isubcase, analysis_code, sort_method, count,
 superelement_adaptivity_index, pval_step, table_name_str)

For a modal problem, analysis_code = 2, which will simplify the op2 output
