**Describe the bug**
The title says it all: if a `List` page is in View mode, and no records are within its Table/filter, then the `DataCaptionExpression` the developer sets is ignored and not shown at the top.

A `DataCaptionExpression` that depends only on the page filters or some other non-record-specific data is not possible in view mode; it just does not get shown. This harms developer and user experience. For instance, a page of 'entries' that can be attached to any specific record - ideally we should see the record type/ID as the caption, but this breaks it.

**To Reproduce**
```al
page 50100 TestList
{
Caption = 'Test List';
DataCaptionExpression = DataCaptionExpressionText;
PageType = List;
SourceTable = "Customer";
SourceTableView = where(Name = const('impossible'));
UsageCategory = None;

layout
{
area(Content)
{
repeater("Group")
{
field("No."; Rec."No.")
{
ApplicationArea = All;
ToolTip = 'Specifies the No.';
}

field(Name; Rec.Name)
{
ApplicationArea = All;
ToolTip = 'Specifies the Name';
}
}
}
}

var
DataCaptionExpressionText: Text;

trigger OnOpenPage()
begin
DataCaptionExpressionText := 'DataCaptionExpressionText'
end;
}
```

**Expected behavior**
It should be possible to set a `DataCaptionExpression`, regardless of whether any record exist and/or whether we are in View/Edit mode, since it might not depend on fields from the record (e.g. might only depend on the page filters). But currently we don't see the `DataCaptionExpression` on the page if in View mode and no records exist. We **do** see it if in Edit mode (even if no records exist) or in View mode with >=1 record(s) existing.

**Screenshots**
Edit - shows `DataCaptionExpression`:
View - does not show `DataCaptionExpression`:
