Solve checker bugs

[carlosmada22]

@carlosmada22 and @JosePizarro3 when checking an Object Type such as EXPERIMENTAL_STEP.DLS as exported from the main instance, the Checker shows errors like "missing autogenerated code" and "missing Comments". The file contents both fields and therefore these errors displayed by the checker seem to not be real. Would you please review the functionality of the Checker. Thanks!

Experimental_Step_DLS.xlsx

In addition, the Checker seems to still not be checking Controlled vocabularies. I attempt to check the following from main:

Vocabulary_Laser_Type.xlsx

I am using the version checker linked in the current Wiki article https://datastore.bam.de/en/masterdata_definition/definition_of_masterdata
