1. Display all syntax error messages when catching SyntaxException …

   Previously when catching syntax errors in the REPL, we were only showing
   the last syntax error displayed by the ruby output. However, ruby can
   generate multiple syntax error messages within a single SyntaxException.
   For example, this code generates multiple syntax error messages:
   ```
   $ ruby -e 'puts {"key"=>"val"}.to_json'
   -e:1: syntax error, unexpected =>, expecting '}'
   puts {"key"=>"val"}.to_json
   -e:1: syntax error, unexpected '}', expecting end-of-input
   puts {"key"=>"val"}.to_json
   ```
   We can't predict which error message would be most helpful for the
   consumer - we should show both of them.
   
   This commit modifies the string replacement we're doing when printing
   SyntaxExceptions so any number of syntax error lines will be shown
   correctly.
   
   Issue: pry#2102
   The error message of SyntaxError is different from Ruby's one
