Nomad UI 'View Raw File' does not pass region parameter

[gmichalec-pandora]

Nomad version

Nomad v0.11.3+ent

Operating system and Environment details

Debian 9.12

Issue

When using the Nomad web UI to browse files for an allocation, clicking the 'View Raw File' button for an allocation in the region other than the default/local region for the UI host, you get an error:
Unknown allocation "ef0a05a1-496d-9360-a2a7-c2e5c7a0e4a2"
However, adding the &region=global parameter to the url successfully loads the file

Reproduction steps

1. Launch job in region A
2. Access nomad UI in region B
3. Navigate to allocation running in region A, browse allocation files
4. Click 'View Raw File'
