Symbol widget does not handle multiple symbols of the same type at the same address

[negasora]

Version and Platform (required):

• Binary Ninja Version: 5.3.9393-dev

Bug Description:
When there are multiple symbols at the same address, the symbol widget will only display one of them

Steps To Reproduce:
Please provide all steps required to reproduce the behavior:

1. Open a.zip
2. Navigate to foo
3. Open the symbol sidebar widget
4. Notice foo is there
5. bv.define_auto_symbol(Symbol(SymbolType.FunctionSymbol, here, "bar"))
6. Notice the list has bar and foo is gone, but the view still displays foo and bv.get_symbols(here) contains foo as well

Expected Behavior:
The symbol widget should show all symbols defined in the binary, or at least be consistent with what linear/graph shows
