Fix APRS object name extraction for names with special characters
The object name regex only matched [A-Z0-9 ] which missed names with
hyphens (P-K5SGD), hash symbols (#146.760), and other printable ASCII.
Changed to .{9}[*_] to match all valid object names including killed
objects. Also merged the two cond branches so data_extended is tried
first with information_field parsing as fallback.

Removed dead copy_insert/3 tests from db_optimizer_test.
