Does not do Server-Side Search for All Folders for IMAP online

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Setup your IMAP in Thunderbird in online mode (no messages stored locally, 
local indexing (gloda) is not used
2. Install expression-search
3. Do a normal search on the "account" for some mails inside a folder, by right 
clicking the mail account and choosing "search messages" (CTRL_SHIFT_F) and 
"run search on server". 
4. Do the same on expression-search box and extend search to all folder 

What is the expected output? What do you see instead?
I would expect that expression-search would search the whole account just like 
CTRL_SHIFT_F search does when you choose the account in "search messages in" 
selection box.
However, it seems expression-search, when proposes to do search on all folders 
by pressing "enter", utilizes the "gloda" mechanism rather than the 
CTRL_SHIFT_F server-side search. Accordingly, as gloda does not have anything 
to index (online IMAP), nothing is returned. Search is not sucessful.

What version of the product are you using? On what operating system?
Thunderbird 17.04, Windows 7 x64, EXpression Search 0.8.4.

Please provide any additional information below.
With the current setup, when using online IMAP and not storing message contents 
in Thunderbird, I can only search with Expression-Search in one folder only. 
When I ask it to extend the search to all folders, the gloda search window 
appears and of course finds nothing. It shall rather use the conventional 
search mechanism invoked by CTRL_SHIFT_F and extend search to the top level of 
that account (at least, or with configuration).
