bugs fixes:

• in mass import, if the sample had to be associated with a container, the creation of the movement failed as well as the import of the whole file
• a database query failed when a subsampling move was displayed
• if the table containing the version numbers was not accessible, the application displayed an incorrect message
• if the parameter table was not accessible, the application crashed with an error message
• exporting, then importing a list of samples (for exchange with other databases) did not take into account the referent
• when consulting a sample, after having clicked a second time in the reference zone, the display was replaced by the label undefined
