Just like we check for an initial decimal separator in ScanStartString()
when the string doesn't start with a currency symbol, check for an
initial decimal separator after the currency symbol too. Without this,
"$.nn" gets parsed as a text field with "$.nn" instead of a numeric field
with $0.nn.

Add a subsequent JUnit test for this too.

Fixes: https://bz.apache.org/ooo/show_bug.cgi?id=82687
- Text entry or CSV import treats $.nn as text
