dirlog update - nuked dirs duplicated

[kijdam]

Hi,

Just noticed after running multiple times the dirlog update that it readds nuked directories even if they are already in the dirlog:

DIRLOG: /site/incoming/stuff/DIR1 - 167 Mbytes in 14 files - created 26 Mar 2017 07:44:01 by 206.500 [1]
DIRLOG: /site/incoming/stuff/DIR2 - 196 Mbytes in 16 files - created 26 Mar 2017 07:44:00 by 206.500 [1]
DIRLOG: /site/incoming/stuff/DIR3 - 218 Mbytes in 18 files - created 26 Mar 2017 07:44:01 by 241.900 [1]

[12:39:22] [L] site search DIR1
[12:39:22] [L] 200- (Values displayed after dir names are Files/Megs/Age)
[12:39:22] [L] 200- Doing case-insensitive search for 'DIR1':
[12:39:26] [L] 200- /incoming/stuff/DIR1 *NUKED*
[12:39:26] [L] 200- /incoming/stuff/DIR1 *NUKED*
[12:39:26] [L] 200- /incoming/stuff/DIR1 *NUKED*
[12:39:26] [L] 200- /incoming/stuff/DIR1 *NUKED*
