Cannot create new builds with configuration containing dash (-) in its name.

[CristianoYL]

Issue description

When trying to create a new build, the process would fail if the configuration name contains a dash (-). The logs from the hub shows a 404:

WARNING:tornado.access:404 OPTIONS /build/my-test-config/new (172.17.0.1) 0.97ms

If we used underscore (_) instead, it would work.

Steps to reproduce

• Go to Builds -> Menu -> New configuration.
• Enter a configuration name that contains dashes (e.g. test-config) and fill in other required fields as usual.
• After the configuration is created, select Menu -> test-config -> Create new build
• No build gets created after submission. (ERROR HERE)

Additionally, if the build name contains dashes(-), the similar error would occur when we try to manipulate it (e.g: deleting a build). The build would not get deleted, and the log shows similar 404:

WARNING:tornado.access:404 OPTIONS /build/test-new-build (172.17.0.1) 0.66ms
