Relative paths are treated differently in different commands

[ms14981]

Assuming a file path blah/forge/openapi-forge-javascript/package.json and blah/forge/openapi-forge/package.json with the following commands run from the blah/forge/openapi-forge directory.

$ ./src/index.js generator-options ../openapi-forge-javascript
$ ./src/index.js test-generators --generators openapi-forge-javascript

We are running the commands from the same location. The generator is installed in the same directory. But the generator-options command requires ../ whereas test-generators doesn't! See also #186

To complicate matters, if openapi-forge is installed globally, then the relative path is interpreted as relative to the location that the openapi-forge global package is installed, which would only work if the generator is also installed globally:

$ openapi-forge test-generators --generators openapi-forge-javascript
Starting tests for generator openapi-forge-javascript
cd: no such file or directory: C:/Users/<username>/AppData/Roaming/npm/node_modules/openapi-forge-javascript

TODO:

1. Change the test-generators command to be consistent with the generator-options command.
2. Fix relative paths for global call of openapi-forge.
3. Update the documentation!

One thing to note here, the test-generators command operates a little differently from the forge command.

With the test-generators command you specify which generators you would like to test, however, these are not installed via the 'resolver', instead they are expected to be available locally, and in the same folder as the forge.

This was originally done in order to simplify the relationship between the two. Previously generators had a dependency on openapi-forge which meant that they installed them (in an npm_modules) sub-folder, which resulted in a confused situation, whereby there was both a 'global' openapi-forge (which runs the test-generators command), and local copies for each generator.

Of course, the current situation, where the two commands perform differently isn't ideal.
