doveadm sync ignores -u option

Hi,

Since I upgraded from 2.2.21 to 2.2.23, the user option -u seems to be ignored by doveadm sync, or at least it doesn't handle it correctly.

If I run the following in the shell as user 'max':

% doveadm sync -u foo@example.com -d

doveadm(max): Error: User doesn't exist

I get it to work if I set the USER environment variable to foo@example.com:

% USER=foo@example.com doveadm sync -u foo@example.com -d

# sync runs as expected.

Kind Regards,

Max
