Img Compressor csv log and console missing line for 1st item compressed

[philoushka]

Repro:

• empty your imageoptimizer-cache.xml (not really required)
• load a directory with n new img files
• run the compressor console
• view the console and csv log

Expected: n entries in the console output and csv log. All images are compressed.

Actual: n-1 entries in the console and csv log. All n images are compressed.

I noticed this while debugging in the console as well. It was the first item that isn't reported.
