'occ' returns no OBIS records if 'limit' is increased

[AMBarbosa]

The 'limit' argument seems to be causing strange effects on the OBIS records returned by the occ function. Not only does it announce more occurrences returned than found (as reported before, in #261), but if I increase the limit, no OBIS records are returned:

> spocc_data <- occ("Phaxas adriaticus", from = c("gbif", "obis"), limit = 10000)
> spocc_data
Searched: gbif, obis
Occurrences - Found: 213, Returned: 10,213
Search type: Scientific
  gbif: Phaxas adriaticus (213)
  obis: Phaxas adriaticus (10000)

> spocc_data <- occ("Phaxas adriaticus", from = c("gbif", "obis"), limit = 20000)
Warning messages:
1: obis: No records returned in OBIS for Phaxas adriaticus 
2: obis:  
> spocc_data
Searched: gbif, obis
Occurrences - Found: 213, Returned: 213
Search type: Scientific
  gbif: Phaxas adriaticus (213)
