rawfolder is not in sync with the current architecture of the data on disks

[jiho]

Due to the recent changes, the rawfolder field of the db needs to be changed.

The current prefixes are

FTP/Ecotaxa_Data_to_import/
ftp_plankton/Ecotaxa_Data_to_import/
ftp_plankton/UMaine/
local_plankton/uvp/uvp5_missions
local_plankton/uvp/uvp6_missions
local_plankton/uvp/uvp_a
local_plankton/uvp/uvp_b
local_plankton/uvp/uvp_c
local_plankton/uvp/uvp_d
local_plankton/uvp/uvp_reglages
plankton/uvp5_missions/

Some should be changed according to

ftp_plankton/ -> FTP/
local_plankton/uvp/ -> plankton/
uvp_a -> uvp_reglages
uvp_b -> uvp5_missions
uvp_c -> uvp6_missions
uvp_d -> uvp_dvlpt

Adding "production" tag as it's not a bug.
