Don't fail loading a message with an empty part

For some valid email, the body is an empty file. For instance:

$ ll $HOME/.qmf/mail/1487871842.4702.EL1S3-parts/
total 148
-rw-rw-r-- 1 nemo 147427 Feb 23 18:44 2.2
-rw-rw-r-- 1 nemo    188 Feb 23 18:44 2.1
-rw-rw-r-- 1 nemo      0 Feb 23 18:44 1

In that case, the part loader of the content manager plugin is returning false
because after loading the body of part 1, it fails the test part.hasBody(),
resulting in the message being not loaded because one part fails. This test
makes sense to check that there was no obvious error while loading the file,
but it is not properly handling the case when the file is empty.

Anyhow the empty file was created or if it makes sense or not, the part loader
should not fail in that case because the part exists on disk and is readable,
but simply empty.
