Matthijs Kooijman af8e1e6dc4 Tests: Do not read system user's data
The tests would initialize Base, PreferencesData with default settings
and/or run the arduino executable, without specifying any settings to
use. In practice, this would read settings from e.g. `~/.arduino15`,
load libraries from the user's sketchbook, etc.

This is not a good idea, since this can be influence the test. For
example, the presence of invalid libraries would cause extra output to
be generated, which breaks the `--version` test. Or having the "Use
external editor" setting set would break tests that try to edit a
sketch.

This commit fixes this. The core of this commit is in
`AbstractWithPreferencesTest`, which sets up a clean settings dir (to
replace `~/.arduino15`) with a sketchbook and `preferences.txt` file
inside before every test (and removes it again after the test.

For some tests, this is enough, but some tests create an instance of
`Base`, which again initializes everything, including preferences, from
the default location. To prevent that, `--preferences-file` is passed to
the `Base` constructor, loading the previously set up preferences. This
is handled by the new `AbstractWithPreferencesTest.createBase()` method.

Furthermore, CommandLineTest calls the actual Arduino executable, which
has the same problem. This is fixed by passing the same
`--preferences-file` option on the commandline (generated by
`AbstractWithPreferencesTest.getBaseArgs()`).

This should prevent all tests from reading the the default settings
files, fixing some tests on my system and even speeding up the tests
somewhat (due less libraries and cores to load, probably).
