Test document contains macro

Reported in:

Open the attached document and click "Execute macro" field to open the dialog. 
There are two combobox, one is dropdown enabled (ComboBox1) and another is diabled placed below (ComboBox2).
- Push "Info" button on the dialog
-> opened messagebox shows number of count of actions. ComboBox1 should have 1 action and another should not have any actions.
- Push "Action 0 for box1" button on the dialog.
-> It tries to execute doAccessibleAction method with action index 0. But it shows on AOO 4.1.0.

It worked on 4.0.1.

VCLXAccessibleBox::getAccessibleActionCount method returns 0 for m_bIsDropDownBox is true and 0 for false. 
But it should be 1 for true, 0 for otherwise.

Proposed patch to change number of accessible actions for dropdown enabled

The patch contains to change count of accessible action for dropdown enabled box. 
I found the problem in getAccessibleActionDescription method and it related to 
this subject.

I met another problem after the above fix. When I choose an entry from the dropdown box 
shown by the accessible action, the office crashed. 
Because m_xText instance variable is already non-valid reference after the dropdown 
is closed that shown by the accessible action in 
case VCLEVENT_COMBOBOX_SELECT of VCLXAccessibleBox::ProcessWindowEvent method.
After the attached patch, the crash is not happen. But the later part of the 
VCLEVENT_COMBOBOX_SELECT is never happen, it seems.
