TimeEntry.Equals returns false on same object

[AtomCrafty]

Apparently TimeEntry.Equals sometimes returns false when passed the same object it was called on:

> entry.Equals(entry)
false

Note that we are using custom fields, but entry.CustomFields.Equals(entry.CustomFields) returns true, so it shouldn't be the cause.

We temporarily fixed it by replacing _localEntries.Remove(entry)
by _localEntries.RemoveAll(l => l == entry), but this should be looked into :)
