When value defined in multiple backend, last one wins

[dmaciel]

This was previously discussed in #7, but my tests are giving different results, If I define a variable in a file as an env var, the last backend on the list wins

Examples:
l := confita.NewLoader(file.NewBackend(path),env.NewBackend())
in this case the env backend overwrites the values in the file files

n := confita.NewLoader(env.NewBackend(),file.NewBackend(path))
same issue here, the file will overwrite any value previously set as env var

The docs say: "Confita scans a struct for config tags and calls all the backends one after another until the key is found" from my understanding once found it stops and continue looking for the next config key

There is a working example of the issue:

Thanks to @rogpeppe for your go playground example on issue 61
