fix(solid-start): #269 fix build of solid-start apps

When running vinxi build on a Solid Start app the project builds in the following order:

- Router ssr at base path /_build
- Router client at base path /_build
- Router server-fns at base path /_server

Based on this we can see that the isEnabled fn will only return true on the last phase of the build. In practice this means the build fails on the first step due to missing files in the codegen directory.

With this change the isEnabled flag is true for the first step which is the ssr one.
