Bugfix: Correctly display parseError in PhenotypeUploadWizard

Autobean has issues with "has" getters. They don't get serialized for some
reason. Changed to "is" getter.

Bugfix: Disable submit button when there are parseErrors

The hasParseError flag is properly set, when there are parse errrors.
Enhancement: Check phenotype values for parse errors and drop them

The HelperService now checks if the phenotype values are valid (using supercsv
CellProcessors). The TraitUomService will drop all phenotype values that are not
valid.
Bugfix: Checks if CellProcessor is a CellProcessorAdaptor before casting

Two fixes:

- Added a branch to check if Adaptor is of type ParseLong
- Checks adaptor if it is of type CellprocessorAdaptor before casting
