Added new getAnnexesExcludingTag function.
Refactored using hbUtil.getAnnexesExcludingTag
Propagate $attrs.hbAnnexesUploadNoValidation to $scope.
Let attribute hb-annexes-upload-no-validation='true' disable valid
elfinForm state for special validation case such as mandatory annexe
validation in CONSTAT form.
Maintain annexesNoPhotoNb count in $scope for elfinForm binding to
benefit from input type number built-in min validation constraint.
Added new hb-annexes-upload-no-validation
Make at least one annex mandatory.
Fixed scope conflict between several hb-annexes-upload directive use.
