/** 
Retrieve the field text for the given field type and contact item ID.

The behaviour differs when a specific field type is not given i.e. when
aFieldType is KUidContactFieldMatchAll:

- First tries to find an email for the given contact item ID.
- If there is no email then it retrieves the first entry in Fast Access fields
for the given contact item ID.
- If there is no Fast Access fields then it retrieves the first entry in the
text fields blob for the given contact item ID.

Text for all other field types are retrieved from the text fields blob.

The caller must determine that the given contact item ID exists before calling
this method.
