parse_date_time on dates with weekdays fails when weekday (a / A) is specified in order

[Henrik-P]

If dates contains a full or abbreviated weekday, parse_date_time fails if weekday (A or a) is specified in order. However, such dates are parsed correctly if weekday is not specified in order:

dat <- c("Saturday 31 August 2013", "Sun 12 Jan 2014")

parse_date_time(x = dat, orders = c("a d b y"), locale = "eng")
# [1] NA NA
# Warning message:
# All formats failed to parse. No formats found. 

parse_date_time(x = dat, orders = c("A d b y"), locale = "eng")
# [1] NA NA
# Warning message:
# All formats failed to parse. No formats found. 

parse_date_time(x = dat, orders = c("d b y"), locale = "eng")
# [1] "2013-08-31 UTC" "2014-01-12 UTC"
