/p/new is not handled by the URL-to-postName parser

[RamRS]

Hi,

Using the URL https://www.biostars.org/p/new/post/?tag_val=GATK by pasting it directly or in the format [https://www.biostars.org/p/new/post/?tag_val=GATK](https://www.biostars.org/p/new/post/?tag_val=GATK) breaks the parser - it shows Post not found?tag_val=GATK, as it tried to parse /p/new/ and fails. However [random text](https://www.biostars.org/p/new/post/?tag_val=GATK) works fine. This is a niche bug, but still needs to be fixed IMO.
