Datepicker: longDateFormat is in defaultFormat not in locale specific format

[SidekickJohn]

In format.ts when expandFormat is called, the specified _longDateFormat is not used properly to format the Date.

Using ngx-bootstrap 1.9.2.
Example:
I picked 'de' as locale which has: 'DD.MM.YYYY' as a _longDateFormat "L".

In File format.ts:
Looking into expandFormat() --> locale.longDateFormat(L) is set.
When format.replace(localFormattingTokens, replaceLongDateFormatTokens) is called, the locale specific part gets missing somehow.

In file locale.class.ts:
The locale specific formatting is lost and the default-format for L is used.

This results in a date that is formatted: 'MM/DD/YYY'.
