Using `BACKUP_NAME` with empty `BACKUP_PREFIX` doesn't work at all

[firehist]

testIt () {
  local backupPrefix=$1
  local backupName=$2
  local name=''

  if [ -n "$backupName" ]; then
    name="1"
  else
    name="2"
  fi
  echo "$name"
}

BACKUP_PREFIX=
BACKUP_NAME=jenkins

echo $(test $BACKUP_PREFIX $BACKUP_NAME)
# Ouput 2

BACKUP_PREFIX="beurk"
echo $(test $BACKUP_PREFIX $BACKUP_NAME)
# Output 1

I've made that PR. The idea is if that you define $BACKUP_NAME it overrides everything else. So it will end $BACKUP_NAME.tar.gz (pretty useful if you use S3 versions) with life cycles. So it doesn't make to define $BACKUP_PREFIX and $BACKUP_NAME at the same time.

Maybe it's confusing and should warn that PREFIX shouldn't be defined …

Currently I'm using this in prod with no problem
