Crash in DevTest

[Watilin]

Pipeworks causes a crash in DevTest because it incorrectly assumes the existence of mapgen water nodes.

Steps to reproduce

• Install Development Test from whatever source you prefer (I used Luanti's content browser)
• Install pipeworks and its dependencies
• Create a DevTest world and enable pipeworks and its dependencies for this world
• Select the world and click “Play”

Expected results

The game should run.

Observed results

The game crashes at startup with this message:

Interesting. Pipeworks doesn't claim to work with devtest but also not that it doesn't ....

Maybe this should be dealt with by [xcompat]?

pipeworks needs to handle that alias not being set
