[IMP] tests: allow standalone tests to use ~ in addons-path

Using `./odoo-bin` to start Odoo, the addons path can contain a `~`, eg
`~/Documents/whatever`.
Those `~` are accepted and work both with the `--addons-path` passed as
the command argument, or in the `.odoorc` config file.

The `@standalone` tests (launched with `./test_module_operations.py`)
however did not work with that `~` as the path was not "normalized".
Neither a `~` in the config file or in the `--addons-path` argument were
working.

While it is not very critical, it is a nice to have to have the same
behavior as the `./odoo-bin` as this made me lose quite some time
figuring why I couldn't use my usual `design-themes` repo addons path.
