workDir terminal argument doesn't affect launcher_log location on linux

After installing the launcher on linux from the tarball under "other", I attempted to run it somewhere other than ".minecraft" using "--workDir"; this results in everything I knew to look for being placed in the expected directory, except the launcher log which was placed in ".minecraft"

Steps to Reproduce

1) Download the minecraft launcher as a tarball from the official minecraft website

2) Run the launcher from the terminal, passing it the workDir argument. For instance:

mkdir launchertest
./minecraft-launcher --workDir launchertest

Observed Results

The launcher's files are for the most part put into the correct folder which you just created. However, the "launcher_log.txt" file is always places in "~/.minecraft" no matter what you specify

Expected Results
The "launcher_log.txt" file would be placed alongside the other launcher files when using "--workDir".
